ROAD-GRADER.

Specification of Letters Patent.

Application filed March 27, 1908.

Patented Jan. 19, 1909.

Serial No. 423,754.

T 0 all whom it may concern:

Be it known that I, LEVI IRELAND, a citizen of the United States,residing at Fredericktown, in the county of Knox and State of Ohio, haveinvented certain new and useful Improvements in RoadGraders, of whichthe following is a specification.

My invention relates to an improvement in road graders, and the objectis to provide a blade which can be reversed or shifted from one positionto another.

Another object is to provide means for reversing the position of theblade and for holding the same in its reversed position.

The invention consists of certain novel features of construction andcombinations of parts which will be hereinafter fully de scribed andpointed out in the claims.

In the accompanying drawings Figure 1 is a top plan view Fig. 2 is aview in side elevation; Fig. 3 is a rear view Fig. 4 is a bottom planand Figs. 5 and 6 are details.

A represents the frame and 1 is the crossbeam. A beam 2 extends from thecrossbeam 1, and extending from the ends of the crossbeam are braces 3,3, which are connected to the outer end of the beam 2. A truck 4 ispivotally connected to the end of the beam 2 and to the truck 4 a draftappliance is connected whereby horses or draft animals can be attached.A blade 5, which extends beneath the frame, is pivotally connected tothe beam 2 by a bolt 6. This blade is connected to standards 7, 7, whichextend downwardly from the crossbeam 1 by hinges 8, 8. Connected to thehinges at their central pivotal connection is a link connection 9. Astem 10 passing through the beam 1 is connected to the link connectionand a handle 11 on the stem is adapted to be turned for operating thehinge to draw one end of the blade 5 inward or to throw it outward. Theend of the blade being operated will cause the other end to be thrown inthe opposite direction from the movement of the end which is beingoperated. The crossbeam 1 is preferably made of angle iron and the linkconnection is adapted to bear against the beam when the hinge is thrownto its extended position.

Wheels 12, 12 are journaled in bifurcated ends of shanks 14.- Theseshanks 14 are adapted to slide in guideways 15, 15 in the standards 7.

Levers 16 are pivotally connected to the crossbeam and are connected tothe shanks 14 by links 17. The levers 16 are adapted to raise and lowerthe wheels to the position desired and are held in such-position by thedogs 18 on the levers engaging the rack-teeth in the segments 19. A seat20 is secured in any suitable manner to the central beam 2 for thedriver or operator.

The blade is capable of being shifted from one side to the other orcapable of a reverse movement to accommodate the direction of travel ofthe grader for throwing the dirt in the direction desired. Again therear wheels 12 can be so adjusted as to cause one end of the blade tocut into the earth for digging a trench or ditch along a roadway.

It is evident that more or less slight changes might be resorted to inthe form and arrangement of the several parts described withoutdeparting from the spirit and scope of my invention, and hence I do notwish to limit myself to the exact construction herein set forth, but

Having fully described my invention, what I claim as new and desire tosecure by Letters Patent, is

1. In a road grader the combination with a frame, of a blade connectedthereto, hinges connected to the blade and means for operating thehinges whereby the position of the blade can be reversed.

2. In a road grader the combination with a frame, of a blade, hingesconnected to the frame and blade and means for operating the hingeswhereby the position of the blade can be reversed.

3. In a road grader, the combination with a frame, of a blade connectedthereto, hinges connected to the frame and blade, and handles connectedto the hinges whereby one end of the blade is thrown in one direction,and the other end in the o posite direction upon the operation of one ofthe handles.

4. In a road grader the combination with a frame, of a blade pivotallyconnected thereto, means for adjusting the position of the blade, wheelsmounted on the frame and means connected to the wheels for raising andlowering either end of the blade.

5. In a road grader the combination with a frame, of a blade pivotallyconnected thereto, means for adjusting the position of the blade, wheelsmounted on the frame and levers connected to the wheels whereby an endof the blade may be raised or lowered by operating one of the levers.

6. In a road grader the combination with a frame, of a blade pivotallyconnected thereto, means for adjusting the position of the blade, Wheelsslidably connected to the frame, and levers connected to the Wheels forraising andlowering the blade.

7. In a road grader the combination With a frame, of a blade pivotallyconnected to the frame, hinges connected to the frame and blade, linksconnected to the hinges, and

means connected to the links for operating 16 the hinges for adjustingthe position of the blade.

In testimony whereof I afiiX my signature in presence of two Witnesses.

I LEVI IRELAND. Witnesses:
